A 2-player game will always be played from the first stage and cannot be continued from higher stages (with the exception of Continues). The second player must also have a copy of the game to play. Due to system limitations, a 2-player game is only possible via a Game Boy Advance Link Cable.Additionally, passwords exist that allow to start between stages 2 to 6 with 99 lives. A Continue Game option was added, which utilizes a password feature allowing a player to start on any of the five stages after the first stage.This version only has two difficulty levels: Novice and Normal, with Novice mode cutting the game's length at the end of Stage 4.The music from these removed top-view stages, however, was retained and play in their respective stages. The top-view stages ( Stage 2 and 5) from the original Super NES game were replaced with two stages from Contra: Hard Corps ( Military Train and Big Battle).

The player can now lock their character's aim like in Contra: Shattered Soldier, allowing them to move anywhere while shooting at one direction.
